STAPLE OR HOLDING DEVICE.

Application filed September 26, 1922. Serial Ho. 590,680.

To all whom it may concern:

Be it known that we, HENRY LLOYD Coon- BAINE, residing at 42 Brecknock Road, Knowle, Bristol, England, and MATTHEW GEORGE FRY, residing at 19 Breach Road, Bedminster, Bristol, England, both subjects of the King of Great Britain, have invented a new and useful Improved Staple or Holding Device, of which the following is a specification.

Our invention relates to staples and more particularly to staples for securing the corners of wooden frames or for other articles where two pieces of wood join each other at an angle. One object of our invention is to provide a staple which will not split the wood and at the same time will make a strong and efficient joint.

In the drawings Fig. 1 is an elevation of one form of staple made in accordance with this invention;

Fig. 2 is a perspective view of the same, while Fig. 3 is a plan'view showing the staple as applied to the corner of a rectangular wooden frame.

The staple or holding device can be formed from any flat metal and is composed as usual of a connecting or mid portion with a prong at each end projecting at right angles thereto. The widthwise angle between each prong and the connecting portion is such that the connecting portion a, has a trapezoidal form when viewed in plan and when the prong are driven into the wood the width of the prongs will lie parallel to the grain of the wood into which they are driven and the ends of each prong, if they protrude from the other side of the wood when the prong is driven in, can be turned over to lie across the grain of the wood.

In the drawings, we have shown, as one application of our invention, a staple having the widths of its two prongs I) each at an angle of 45 degrees to the width of the portion a connecting the two prongs, the two prongs thus'being at right angles to each other, and the lengths of the prongs being in planes at right angles to the length of the connecting portion, as usual. It should be noted that in any staples made according to our invention the angling of the prongs relatively to the connecting portion is such as to give the connectingportion a trapezoidal form when viewed in plan (see Fig. 3). A staple formed with these angles between the widths of the prongs and the width of the connecting piece is especially adapted for use in securing a rectangular corner of a picture frame. Thestaple is shown applied to such a corner-in Fig. 3. The connecting portion a of the staple crosses the joint formed by the two sides 0 of the frame at right angles thereto, and the prongs pass through the woodof each side 0 parallel to the grain. The protruding ends of the prongs, on being turned over as shown at 6 lie against the respective sides a transversely to the grain of the wood.

lVhat we claim is:

1. A staple made from flat strip metal with the prongs at substantially right angles to the mid-portion which connects them, the

prongs being so bent with respect to the mid-portion that said midportion is of trapezoidal form in plan.

2. A staple, or holding device, formed from strip metal with the end portions, or

prongs, in planes at'right angles to the midportion which connects them and the said end portions, .or prongs at right angles to each other.

In testimony whereof we have signed our names to this'specification in the presence of two subscribing witnesses.
